APPARATUS FOR CONVEYING MATERIALS.

Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, HEINRIon HORN, a subject of the King of Prussia, German Emperor, residing at 12 Biesnitzerstrasse, Go'rlitz, in the Kingdom of Prussia and Empire of Germany, have invented new and useful Improve ments in Apparatus for Conveying Materials,

of which the following is a specification.

My invention relates'to apparatus for conveying tenacious or sticky materialsuch as moist clay, loam, and the like-by means of a drag-chain, which takes the material automatically from a feed-receptacle and mixing it in a lon channel adjoining the said receptacle con ucts the same in equal quantities to machines. The material, which is uniformly distributed by means of a leveling means, herein called striking-0d board or scraping-board or scraper, in the spaces between the links of the drag-chain is forced from this chain by one of the. chain-drums, the periphery of such drum being provided with elevations corresponding in size to the spaces between the chain-links and engaging these spaces in the passage of the dragchain. Any material which ma adhere to the elevations can if necessary e removed by a scraper. In order to prevent the material which has been forced from the dragchain by the elevations onthe periphery of the chain-drum from falling back upon the drag-chain and into the conveyer-channel, I provide a catching device as near as practicable to the chain drum. The aforesaid scraping or striking device may at, the same time serve for this purpose, thereby enabling the conveyer-channel, which joins the" receptacle into which the material is thrown, to be utilized completely for mixing the material.

In the accompanying drawings I have shown a constructional form of this invention by way of example.

Figure 1 is a vertical longitudinal section. Fig. 2 is a lan. Fi 3 is a transverse section on the no A B o the apparatus. Fig. 4 is an enlarged view of a portion of Fi 3. Fig. 5 is an enlarged View of a portion'of ig. 1, and Fig. 6 is a fra mentary plan view showing the striking-o board or scraper and we htmeans.

T e endless-drag-chain 12 consists of links cast in one iece and connected with each other by bo ts c, fixed therein by riveting. This chain is conducted over two chaindrums d'and e. The lower chain-drumd is keyed upon a shaft g, held in two bearings f, while the upper chain-drum e is fixed upon the shaft 71., which is held in the two bearings i and adapted to be set in rotation by the belt-pulley 1c. Whereas the lower chaindrum d consists, as usual, of two toothed disks serving to guide the drag-chain b, the upper chain-drum e forms a c linder having recesses for the transverse ars of the links of the chain b. This drag-chain passes over the cylindrical drum e and its upward bars en'- gage the recesses in the drum. The up wardly-moving art of the dragchain 1) slides in the weli known manner upon the plate or bottom Z, which, together with the walls m, strengthened by beams 7', forms between the two chain-drums d and e the feedreceptacle a. and the conveyer-channel joining such receptacle.

The links of the chain b,sliding upon the plate or bottom Z, form rectangular spaces b, which are filled up with the material that lies in the feed-receptacle a or is thrown into the same or into the adjoining conveyerchannel. On its way to the top the material taken away by the drag-chain often rolls back and is turned over in order to be again conducted higher up and to partially fall back once more, so that it will become thorou hly mixed in the long channel.

pproximately in the middle of the length of the conveyer-channel I arrange the scrap ing or leveling device designed to remove the excess of material from the drag-chain. This device has a striking-0d or leveling board n,

adapted to bear by its lower edge upon the drag-chain, this board being fitted to move up and down in vertical guides w (see especially Figs. 4, 5, and 6) on the side walls at of the conveyenchannel and subjected to the action of wei hted levers s. The latter can turn upon a olt t, fixed in the side walls m of the conveyer-channel and. are furnished with adjustable ei hts '11., slidable on the levers or arms .9 and c amped in the desired position by screws u Their downward movement is limited by these weights u bearing in their lowest position upon a stop 1; in the form of a transverse bar. Moreover, the action of the weighted levers s u on the scraping or striking board 42 can e regulated, the former transmitting their pressure to the scraping or striking board n through the intervention of screws 0;,- adjustably carried by the levers or arms 3 and which bear upon the upper edge of the movable scraping or striking-off board n. Said board n retains the material 8, lying in heaps between the links of the drag-c ain b, and s reads it out. As a consequence, the

s aces between the links of the chains are a ways quite filled up, and the links do not carry away more material than can find room between them. In case there are large stones between the links the sore ing or striking-0E board n will be lifted a ainst the counterweights a and will imme iately be lowered again after the passage of the stone.

By its cylindrical races, which form elevations, the upper chain-drunr e forces the ma-- terial lying in the spaces 1) between the links of the drag-chain from between these links and throws it off. Part of the material thus ejected will fall back into the conveyorchannel. In order to catch up the material which may fall back, I provide a catching de vice in front of the point where the drag chain runs onto the upper chain-drum e. The said catching device comprises a flap y, adapted to move about hinges z in the direction 0i motion of the drag-chain and pre- 0 5 vented b sto s j to move in the other direction. T us t e flap can yield to large stones, so as to let them pass, and prevents the material from falling back into the channel. It will be seen, therefore, that the material will be uniformly carried away by the drag-chain b and that the quantity will depend upon the free spaces b between the links and that the speed of delivery will be proportionate to the speed of movement of the chain b. o

For particularly tenacious or adhesive ma terial I have arranged between the lateral beams p a scraper 0, which extends to the cylindrical faces of the drum 6 and scrapes any adhering material off the drum 6.

In case the scraping or leveling device, with the movable scraping-board n, is arranged immediately in front of the point where the drag-chain runs onto the upper drum ethe material forced out by the latter 4 5 will be prevented from falling back into the conveyer-channel, thus enabling a special catching device to be dispensed with.
